Barrage de Fully, Gravity dam and hydroelectric facility in Fully, Switzerland.
Barrage de Fully is a gravity dam positioned across the mountain valley that holds back water for power generation. The structure harnesses the natural alpine elevation to store water and convert its flow through turbines into electricity.
Construction started in 1912 and was completed in 1914, with workers relying on steep mountain paths and funiculars to move materials up the slopes. This project marked Switzerland's early push to develop hydroelectric infrastructure in the Alps.
The dam shows how Switzerland tapped into water power early on, reshaping the mountain valley in the process. Visitors can observe how energy flows from water and how essential this waterway remains for the region.
The site sits at high elevation and can become difficult to reach during bad weather. Bring sturdy footwear and allow extra time to explore the surrounding landscape safely.
When completed, this dam featured a remarkably steep water drop of more than 1,600 meters, which set a world record at the time. This record stood until another dam surpassed it decades later.
